Definitions

the present invention relates to the field of household appliances comprising a tank for generating pressurized steam and a supply circuit configured to supply the tank with water from water contained in a tank.
An ironing and / or smoothing appliance comprises, in a known manner, a tank, a tank for generating pressurized steam, and a supply circuit configured to supply the tank with water from water contained in the tank, the supply circuit comprising a pump and, downstream of the pump, a bypass circuit configured to return part of the water from the pump to the reservoir.
Such a bypass circuit makes it possible, on the one hand, to facilitate the priming of the pump when the ironing and / or anti-crease appliance starts up, or when the ironing and / or anti-crease appliance is used for the first time, or when the reservoir has been completely emptied beforehand, and on the other hand to evacuate any air bubbles present in the pump to the reservoir.
a drawback of such a bypass circuit lies in the fact that, when the ironing and / or anti-crease appliance is stopped, the pressure in the tank decreases (due to the cooling of the tank), and causes a suction effect in the bypass circuit so that the water contained in the bypass circuit is sucked into the tank.
Such a configuration of the delivery chimney makes it possible, because the latter opens above the maximum filling level of the tank, to prevent the water contained in the tank from being sucked into the bypass circuit and into the tank, and therefore to limit the quantity of water which is sucked into the tank.
a discharge chimney having a small passage section can be obtained by manufacturing the reservoir and the discharge chimney by a molding process which uses a relatively complex mold, and which includes in particular an overmolding step during which two parts of the tank , which each partially define the delivery chimney, are overmolded.
the present invention aims to remedy all or part of these drawbacks.
the technical problem underlying the invention consists in particular of providing a household appliance, and in particular an ironing and / or smoothing appliance, the manufacturing costs of which are reduced compared to the appliances of the prior art, while at the same time limiting the quantity of water sucked into the tank when the appliance is switched off.
the present invention relates to a household appliance comprising a tank, a tank for generating pressurized steam, and a supply circuit configured to supply water to the tank from water contained in the tank, the circuit supply comprising a pump and, downstream of the pump, a bypass circuit configured to return part of the water from the pump to the reservoir, the bypass circuit comprising a discharge chimney extending to the inside the tank and opening out above a maximum filling level of the tank, characterized in that the bypass circuit comprises an insert which is attached to the inside of the delivery chimney, said insert filling part of the internal volume of the discharge chimney and forming, with the discharge chimney, a passage channel which fluidly connects the interior of the tank to a part of the bypass circuit which is located upstream of e the discharge chimney.
Such a configuration of the bypass circuit makes it possible to manufacture a discharge chimney having a large passage section with a simple and inexpensive molding process (without overmolding), and then to insert an insert, which can also be made from it. 'a simple and inexpensive molding process (without overmolding), in the delivery duct in order to form a passage channel of reduced section.

the reservoir 8 can for example be made made of plastic material, and be housed at least partially in a receiving location 9 provided on the housing 7.
the reservoir 8 more particularly comprises a filling orifice 10 through which the reservoir 8 can be filled with water up to a maximum filling level 11.
the reservoir comprises a reservoir body 8.1 and a reservoir cover 8.2 which is fixed to the reservoir body 8.1, the reservoir cover 8.2 comprising the filling orifice 10 and a closing flap 8.3 pivotably mounted on the reservoir cover 8.2 .
the closing flap 8.3 can pivot from an open position, shown in figure 5 , in which the filling port 10 is freely accessible in a closed position, shown in figure 2 , in which the filling orifice is hidden by the closing flap 8.3.
the base unit 3 also comprises a steam generator which is arranged in the housing 7.
the steam generator more particularly comprises a vessel 12 for the generation of pressurized steam, and heating means (not visible in the figures). which are regulated to heat the tank 12 so as to produce steam under a pressure greater than 4 bars, and for example of the order of 5 to 6 bars.
the base unit 3 further comprises a supply circuit 13 configured to supply water to the tank 12 from water contained in the tank 8.
the supply circuit 13 comprises in particular a pump 14 which is provided with an inlet port 15, and an inlet duct 16 which fluidly connects the inlet port 15 of the pump to a suction port 17 which is provided on the reservoir 8 and which opens into a lower part of the reservoir 8.
the supply circuit 13 further comprises a water supply duct 18 which fluidly connects an outlet port 19 of the pump 14 to the tank 12, and which is therefore configured to supply water to the tank 12.

the steam outlet 21 is equipped with a solenoid valve
the ironing and / or anti-crease tool 4 comprises a control button 22 configured to control the opening of the solenoid valve when the control button 22 is actuated by a user.
the control button 22 can for example be placed under a handle of the ironing and / or anti-crease tool 4.
the supply circuit 13 also comprises, downstream of the pump 14, a bypass circuit 24 which is configured to permanently return a part of the water coming from the pump 14 to the reservoir 8.
a bypass circuit 24 makes it possible in particular to facilitate the priming of the pump 14 when the ironing and / or anti-crease appliance 2 is started up, either when the ironing and / or anti-crease appliance 2 is used for the first time or when the tank 8 has been previously completely emptied.
the bypass circuit 24 comprises a bypass duct 25 which is fluidly connected to the outlet port 19 of the pump 14 and which extends outside the reservoir 8.
the bypass circuit 24 further comprises a chimney.

the delivery duct 26 is advantageously formed by the reservoir body 8.1 and the reservoir cover 8.2, and has an upper opening 8.4 which is provided on the tank cover 8.2 and which opens into the tank 8 above the maximum filling level 11 of the tank 8.
the bypass duct 25 is more particularly configured to fluidly connect the outlet port 19 of the pump 14 to the delivery duct 26.
the delivery chimney 26 extends substantially vertically when the ironing and / or anti-crease appliance 2 is placed on a horizontal support.
the reservoir 8 and the delivery duct 26 form a single piece, that is to say are made in one piece.
the delivery duct 26 is obtained directly with the reservoir 8 by a molding process.
the bypass circuit 24 further comprises an insert 27 which is attached to the interior of the delivery chimney 26 and which fills part of the internal volume of the delivery chimney 26.

the insert 27 is elongated and extends in an extension direction which is substantially parallel to the extension axis of the delivery duct 26.
the insert 27 is hollow, that is to say it contains a sealed closed cavity which does not communicate with the reservoir 8.
the insert 27 has a shape substantially complementary to that of the delivery duct 26, and comprises a peripheral groove 28.
the cross section of the insert 27 gradually increases starting from a first end face 27.1 of the insert 27 towards a second end face 27.2 of the insert 27, which is opposite the first end face 27.1, so that the insert 27 has a converging shape that is easily demolded.

the passage channel 29 advantageously has a cross section which is substantially smaller than the cross section of the delivery duct 26.
the pressure in the tank 12 decreases (due to the cooling of the tank 12), and causes a suction effect in the bypass circuit 24 of so that the water contained in the suction circuit 24 is sucked into the tank 12.
the quantity of water sucked into the tank 12 is relatively small and therefore does not interfere with the operation of the ironing and / or anti-crease 2 appliance.
the insert may be constituted by a solid part.
the delivery duct can receive several inserts in order to form a passage channel of reduced section.
